| apo koinou |
| Definition: A construction that consists of two clauses that have a shared word or phrase. |
| Example:
I like tennis is my favourite sport.
Here the word tennis is shared by the two clauses I like {tennis} and {tennis} is my favourite sport. Note: The word that is shared by the two clauses — e.g., tennis in the above — is called the koinon. |
| Etymology: The term means "in common" in Greek. |
| Oxford English Dictionary: Its first citation is from 1892: "The whole construction may be apprehended as a sentence with one subject and two predicates. This is the so-called construction apo koinou." (Kellner Hist. Outl. Eng. Syntax 62) |
